I bought a set of old Novatrons off ebay for dirt cheap. The set-up came with a power block, strobes, umbrellas, stands and a nice case. All I had to buy extra was a flash meter. There is plenty of used stuff (barn doors, snoots, etc.) for them on ebay and the company is still in business in Texas if you want new.

If you are interested check out Ken Rockwell's site for plenty of info on Novatrons. He uses them for his website photos of cameras and lenses.
